AUTOMATIC CLOSURE DEVICE FOR- LUBRICA'ISORS.

Specification of Letters Patent.

Patented Feb. 4, 19114.

Application filed October 5, 1912. Serial No. 724,062.

To all whom it may concern Be it known that I, FELIX Brno, a citizen of the Republic of France, and a resident of Versailles, Seine and Oise, France, have invented a new and useful Automatic Closure Device for Lubricators or other Similar Receptacles, of which the following is a specification.

The present invention has for its object an automatic closure apparatus specially in tended for lubricators.

The characteristic qualities of the apparatus consist in the features that the operations of opening and closing are very rapid, that it completely uncovers the lubricating orifice, that it is absolutely tight, and that by reason of its method of fitting it prevents the entrance of dust when it is open and that, moreover, no throwing-out of oil takes place when it is closed.

In the accompanying drawings z--Figure 1 shows the apparatus in elevation, the outer cylinder being removed. Fig. 2 is a longitudinal section. Fig. 3 is a view of the apparatus in the closed position. Fig. 4: is a view of the apparatus in the open position.

The apparatus comprises a body 1 which is fixed upon the receptacle or the object to be lubricated. This body is cylindrical, both internally and externally; at bottom it has a flange or shoulder 2 and at top it is provided with a flanged collar 3. Between the collar 3 and the shoulder 2 there is arranged a spring 4 which presses upon a washer 5, and at the top a closing cap 6 is fitted upon the collar 3.

Two small connections or links 8 at diametrically opposite points connect the washer 5 to the cover or cap 6 by pivots 9. A gasket 7 insures the tightness of the joint. A stiiily-sliding cylinder 10 has at its lower end two elbow-shaped openings 11 allowing the movement of the lower pivots 9 of the links 8. By reason of the frictional mounting of the cylinder 10, the latter can turn at the same time as the links 8 and the cap 6; this allows of opening and lowering the cap in the most convenient position.

Operation: When filling the receptacle or lubricator, the cover is lifted vertically, while turning it in the direction of the slot 11. The spring l is compressed and its force no longer acts upon the links; the latter as cillate freely and move aside the cover 6. The latter swings upon its pivots and completely clears the upper opening of the relilling orifice (Fig. 4). After the filling is completed, the cover is put back and revolved in the direction opposite to the opening movement. lVhen the lower pivots 9 enter the vertical portion of the slots 11 the spring exerts its action and instantly presses the cover upon the stationary body. The tightness of the joint is insured by the gasket 7.

lVhat I claim and desire to secure by Letters Patent of the United States is:

1. In a closure device for lubrioators and similar receptacles, a tubular body having spaced collars, a ring on the body above the lower collar, a spring between the upper collar and ring, a cover for the body, and two links pivotally connecting the cover with the ring.

2. In a closure device for lubricators and similar receptacles, a tubular body having spaced collars, a ring on the body above the lower collar, a spring between the upper CO1- lar and ring, a cylindrical member surrounding the spring and ring and engaging the collars, said member being provided with bayonet slots, a cover for the body, and links pivotally connecting the cover with the ring, the pivots connecting the links with the ring working in the slots of the said member.

In a closure device for lubricators, a tubular body, a ring on the body, a spring pressing upon the ring, a cylindrical member mounted to turn on the body and having bayonet slots, a cover for the body, and links pivoted to the cover and ring, the pivots connecting the links with the ring working in the slots of the said member.

4. In a closure device for lubricators, a body portion formed with a bore extending therethrough, a spring surrounding part of said bore, a removable stop connected with said body portion for holding said spring in place, a ring surrounding said body portion and engaging said spring at the opposite end to that engaged by said step, a cap resting on the end of said body portion and covering said bore, and links connected with said ring and said cap whereby said spring is adapted to resiliently clamp said cap on said body portion.

5. In a closure device for lubricators, a body portion formed with a bore extending .therethrough, a cap mounted on said body portion and covering said bore, a plurality of llnks pivotally connected with said cap arranged on said body portlon, means for connecting said ring and said links whereby said cap may be moved pivotally from ofi' said body portion, and a spring acting on said ring for normally holding the same in a predetermined position and moving the same back to said position when moved therefrom for maintaining said cap on said body portion and over said bore.

6. In a closure device for lubricators, a body portion formed with a bore extending therethrough, a cap extending over said body portion for closing said bore, a spring surrounding said body portion, a stop connected with said body portion at one end forholding said spring in place, a tubular member surrounding part of said body portion including said spring and resting against said stop, said tubular member be ing formed with a pair of bayonet slots, a ring surrounding said body portion positioned in said tubular member and adapted to act on said spring, and links pivotally connected with said cap and with said ring, the pivotal connection between said links and said ring extending through said bayo net slots whereby the cap can be withdrawn from the action of said spring when said cap is moved to an open position.

7. In a closure device for lubricators, a

bod )ortion formed with a bore eXtendin therethrough, a cap posltloned on said body portion for covering said bore, a tubular imember formed with oppositely arranged bayonet slots surrounding part of said body portion, a plurality of links pivotally mount ed on said cap, a ring surrounding said body portion and inclosed by said tubular member, journal members extending from said links to said ring through said bayonet slots whereby said cap may be moved axially away from said body portion and then rotated for the length of said bayonet slots after which the same may be moved pivotally on said pivotally mounted links away from the top of the body portion, and resilient means continually pressing on said ing for causing the same to continually tend to remain opposite the bottom of said bayonet slots whereby said cap is clamped to the top of said body portion.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.

FELIX BLED.
